I Application, filed April 18, 1927. Serial N0.,1 84,527A.

My invention has fory its; principal objectk a turbine pump and direct connected electric motor or,v a turbine water wheel andy direct connected generator adaptedto rotate about al vertical axis wherein all of the radial stresses are substantially balanced and wherein the fluid pump, or fluidv operated in which such a unit is fully disclosed,` myk invention will beV made clear.

Fig. 1 is an elevation partly in yView and partly in section. Y

Figs. 2 and 3 are details in section'and planof an alternate form of glandi i Throughout the figures similar numerals refer to identical parts.

An electric motor is indicated the numeral 1 supportedy uponv the base 2 from the foundation 3.

On the opposite lside Iof the motor is` mounted the 'upstanding pump casing 4, with which is connected the inlet pipe 5 extending' from the casing 4 andthe discharge pipe 7 ,extending from the Opposite side thereoff f y `"Withinthe casing is the volute 9 .which collects thepressure fluiddischargfed onthe vimpeller v10 from which, dueto the pressure imparted to it by the said runner, it is forced through the discharge pipe 7. y

The'impeller or 'Huid rotor 10 is keyed at 11 to the vertical shaft 12. The latter is conveyed through the glands 13 and The lowerV end of this shaft is provided with the vcoupling'head A15, preferably` forged thereon andwhich is adaptedto engage by,

the concentricitongue and groove 1,6 tothe coupling;V head 17 on the motorshaftlS.

The, shaft 18 is carried in the radial guide', bearingl)V on its lowerend and the shaft 12V is carried 'inthe radiall and thrust bearing conventionally: shown at 20, the shaft projecting therethrough and" being supported from they block 21 and nut 22,` the latter engaging' the 'shaft 12 by the threads 23.'

It will' thus be seen that although a sepa# 55 rate shaft is provided for vthe pump a-ndfor the motor, the two, through the engagement of the coupling' parts 15, 17 become', as far' as'their Operation is concerned, the equivalent ofVV an integral shaft.

The ycoupling halves 15, 17 are' bolted together as by studs and nuts 24 and access thereto is had through the opening 25 inthe housing 4. f

The rotor of themotor 1,.not shown butv Q5' well known, ismounted upon the shaft 18 and'drives the impeller 10 which by the pipe 5 is adapted to introduce fluid anddeliver the same in the direction ofthe arrows 26, 26, 26, 26, to the suction or central'openings 7 of the impeller 10, which in turn, through its pump action discharges the fluid into the volute 9 and dischargeY pipe 7 in the conventional manner. f

The unit may of course be positioned as desired'with respect tothe floor, but where employed in large structures, it willl be found advantageous to position the Hoor as shown at 27. f

Within the pump housing-4 is the dia- 90 phragmplate 28 provided vwith drain .ledges ',29-29 under the coupling 17 thus precluding any possibility of leakagewater getting into motor 1. as Afor example when the gland at 14C is being repacled.r c

The motor/1 provides the support for the entire pump structure and the bearing 19 at the end ofthe shaft 18 and the 'combined radial and downward thrust bearing 20 at the opposite or remoteend of shaft 12 form 90 the only necessary .bearings for the combined pump' andv motor.

While I prefer to combine the radial and' thrust bearing 20. at thetop of the l unit and" the single radial bearing '19 at the bottom 95 these maybe Vreversed if desiredfwithoutli departing from my invention. Y, n

Particular attention is directed yto the packing gland shown generally by vthe numeral 14, and which is formed as a separate structure'. yThisis seated on.. a faced' recess on the insideof they housing 4: Vat 41, y

vand securedv by the externally. accessible cap.

screws 42, 43.-

Lifting eye bolts are shown at 44, wheieby upon breaking the joint at 33 and at 41, and removing the coupling bolts 24- 24 at the joint 16 the entire top portion of the unit, with the rotating element including the shaft 12, impeller 10 and gland structure 14, may be lifted.

This enables ready access for repairs or replacement.

An alternate form of packing gland is shown at Figs. 2 and 3 wherein the gland plate is made parting on the joint 51, the two halves 52, 53 being bolted together by suitable bolts-as 54.

Upon removing the cap screws 42, 43, as before and breaking 'the split joint 51, thus allowing the gland plates 52,- 53 to be removed, the top and the entire rotating' element down to the coupling joint at 16 may-be removed and then'by taking out the bearing parts 21, 22, the rotating element 10, 12 may be separated from the removed parts.

.Either of the lgland constructions shown .in Fig. 1 or Figs. 2 and 3 are suitable, depending upon t-he `size and local conditions available in anyparticular plant..

vWhile my invention is particularly applicable to large centrifugal pump units it may also with advantage be employed'for turbines for generating power from falling water.

If the water under pressure be delivered through the pipe 7, the apparatus as shown in the figure of the drawing would function as a turbine generating power in the electrical unit 1 and discharging the expended water through the pipe 5.

The coupling 15,16. 17, it will be noted is positioned within the compartment 30, formedbetween the suction head 31 and the drainpan 28 and may be reached for inspection, lrepaire or replacement through the doorway25.

The bearing 20 is supported from" the `cover 32 and isA connected along the flange joint 33 with the 'pump housing 4.V The compartment 34, vaccessible through the doorway 35 enables the operator lto reach thegland 13.

By disconnecting'at 33 and removing the l bolts between the coupling flanges 15, 17, the

entire rotating element and its surrounding casingV may be lifted vertically from' the housing 4.

Byretaining theV flange joint Aat 33 vand brealringthe flange joints at 36, 37, and 38, the entire hydraulic yunit 'may be lifted vertica-llyI with the rotating` element to getat the interior of the motor. f

Access to :the radial bearing` 19 may be reached through the manhole 39. Y

It will ythus be Aseen that all parts are accessible and may .be easilyand completely dis-assembled, including the separat-ion of the hydraulic and electric portions,'housing and motor frame 2, while maintaining the shortest possible shaft, in a unit of minion one of said parts and a fluid 'rotor mounted on the other of said parts, a casing having a volute therein, said volute having a suction inletpassage and a discharge outlet passage external to said volute and' formed integral therewith, said casing having a flange connection to said stator, a cover member for said Acasing on the opposite side from said flange and having one of saidf bearings mounted thereon, saidA cover having a portion of the walls of one of said passages cast integral'therewith.

2. A .vertical shafthydraulic machine in combination with an electric motor having a stator and a rotorv and including a two part shaft, a radial bearing `at one end of said shaft and a radial and thrust bearing at the other end of .said shaft, a rigid' flanged coupling between the two parts of said sliaft,the rotor of said motor mounted on one of said parts and aA lluid'rotorl mounted-on the other of said parts, a casing having a volute therein, said volute havy ing a suction inlet passage and a discharge f outlet passage external to said volute and formed integral therewith, said easing having a flange connection to said stator, a
